I've been looking again at the CMT Ambisonics plugin sources (1.15), and they just don't make sense and certainly do not work as expected. Some even use two input samples for each output sample on some channels, and whoever wrote them probably never listened to the result.
I've been using the following set for some time: - mono to B-format panner, - stereo to B-format panner, - B-format horizontal rotator, - B-format to square decoder. All of them can be used as Ardour plugins. If there's any interest, I'll release them next WE (I'll be away for work until friday). -- FA
